STOVEPIBE-THIMBLE FOR WALL-FLUES.

Specicaton of Letters Patent.

Patented J an. 10, 1911.

Application filed September 4, 1908. Serial N o. 451,648.

To all whom it may concern:

Be it known that I, PAUL E. BUCKLEY, a citizen of the United States, and a resident of Alton, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvements'in Stovepipe-Thimbles for lVall-Flues, of which the following is a specification.

The invention relates to improvements in stovepipe thimbles for wall flues, and consists in the novel features hereinafter described, and particularly pointed out in the claim.

One object of my invention is to provide a thoroughly durable, efficient and reliable thiinble adapted to stove pipes varying in diameter and to be entirely closed when desired, and a further object of the invention is to provide a thimble which is adapted to protect the wall from the consequences of heat or flames in the pipe, the thimble affording a lire-proof structure.

In carrying out my invention I provide an iron thimble comprising a tubular portion to enter the hole in the wall and having at its outer end an integral annular flat ring face plate to engage the face of the wall, and for the outer end of the tubular portion of the thinible l constructl in a special manner several concentric enlarging and reducing rings and a central closure, said rings being adapted to nestone within the other and in said face-plate and the closure being adapted to nest within the inner ring and complete, when desired, the closing of the thiinble. The several rings and closure are provided with means for conveniently securing them together in series in a very eiiicient manner, and the thimble structure as a whole is of durable character and superior practical utility.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Figure 1 is a central vertical longitudinal section (on the dotted line 1-1 of Fig. 2) through a thiinble constructed in accordance with and embodying my invention, a portion of the wall being shown in section and the several parts of the thimble being assembled and the outer end thereof being closed; Fig. 2 is a front view of the thimble, with the Central closure and the inner ring omitted therefrom, the outer ring being shown in position in the ring face-plate; Fig. 3 is a horizontal section, on the line 3 3 of Fig. 2, showing all of the features of the thimble structure in their vrelative positions for assembling to complete the structure illustrated in Fig. 1, and Fig. 4 is a' rear face view, partly in vertical section and partly broken away, of the entire thinible structure with its parts assembled.

In the drawings, 10 denotes a portion of a wall having an opening 11 leading to a customary wall flue.

The iron thimble of my invention is applied to the wall 10 and comprises a tubular portion 12 which fits within the opening 11 in the wall and is formed integrally with an annular ring face-plate 141 which is adapted to rest against the wall around the opening 11. The face plate is united to the tubular portion 12 by a thickened section 15 in which is formed an annular recess 16 containing an annular flange 17 having at opposite points notches 18 formed therein for the purposes hereinafter explained. The tubular portion 12, face plate 14, thickened section 15 and notched flange 17 are in one integral casting, and said thickened section 15 is of annular formation and projects outwardly beyond the bore of the tubular portion 12 and forms a streng connection between said portion 12 and the face plate la and also, by extending outwardly, leaves the bore of the portion 12 of substantially uniform diameter from vend to end, which I deem to be of considerable advantage. At its lower side the tubular portion 12 is preferably formed with an elongated longitudinal opening 19 leading to a trough 2O which inclines inwardly and downwardly to the flue, and the purpose of which is to receive and discharge into the flue such creosote as may form in the tubular portion 12. rlhe tubular portion 12 is cylindrical and straight except at the trough 20, which is integral with and projects downwardly from the body of said portion 12 and in addition to serving the purposes of a trough pr-events by being within a groove or recess in the opening 11 in the wall, any turning oft-he thimble.

lithin the annular recess 16 of the faceplate 14 is arranged a reducing ring 21, which is of substantially rightangular formation in crosssection and comprises ani outer portion and an inner depressed l portion or tlange 2?, the portion 22 being adapted to seat against the flange 17 and within the recess 1o, so that its outer tace and the outer lace oli the tace-plate 1l Will be flush with cach other, as shown in Figs. 1 and The inner portion or liangc of the ring 21 is concentric With and sets inwardly beyond the inner edges oit' the outer portion 22 or said ring and is adapted to receive a further reducing ring 241, and said tlange is formed at opposite points with notches or openings 25 corresponding With the notches or openings 1S in the flange 17. lhe ring 21, which 1 terni the outer ring, is formed at opposite points with lips 2G Which are at the inner side ot` the tlange 23 and extend outwardly beyond the same, so as to leave a delinite space betn'een the outer taces of said lips and the inner tace ot the outer portion 22 of the ring 21, as shon'n in Fig. The purpose ot the lips 2o, arranged as described, is to lock the ring 21 'Within the recess 16 ot the. tace plate 111-. ln applying the ringl 21 to the tace plate l-fl- 1 more the liijis 26 inwardly through the notches 18 in the flange 1T and then gire to the ring 21. a partial rotation, thereby carrying the lips 2o along the inner surface or the flange 17 and avay 'from the notches 1S therein, said tlange 1T being thereby enga ged between the lips 26 and the portion 22 olf the ring 21 and serving to lirmly support the ring The inner ring 211 corresponds in construction with the outer ring 2l and it is of substantially right angular torni iu cross-sec tion and has an outer portion 2T adapted to seat Within the recess formed by the junction of the parts 22, ot' the ring 21, so that its outer surlace inay be flush with the outer surface oit the outer ring 2l and tace plate 1l, as shown in Fig, 1. The ring 2st has an inwardly extending flange 28, which, at opposite edges, is Ylormed with recesses 29 corresl'ionding with the recesses 25 ,in the ring 2l, and at two opposite points is YFormed with lips 1:30 corresponding with the lips 26 ol the outer ring 21. 1n applying the outer ring 2l to the inner ring 21, 1 more the lips 30 of said inner ringl through the recesses 25 or the outer ring and impart to said inner ring a partial rotation, thereby carrying said lips 3G troni the recesses 25 and causing them with the outer section 27 ot the ring to einbrace the flange 2B ot the ring 21, whereby said flange enabled to firmly hold the ring 2st in position.

1 may provide as many of the reducing and enlarging ringo 21, 2*1, as may be desired, butl usually two of said rings will be sulhcient, said rings enabling me to either reduce or enlarge the opening to the tubular portion 12 to suit stove pipes varying in l diameter. The rings 21, 2d are exactly alike, except that one is smaller than and adapted to nest in the other, While both rings may, when desired, be nested Within the :tace plate 111 and therewith present a llush front.

.fl-s a means for stopping up the opening` through the inner ring 241, 1 provide a closure plate 31 Which at its edge is formed with an annular flange 32 to seat Within the ring 24 and against the lange 28 thereof, and 1 also provide the closure 31 at opposite points, with lips 38 corresponding with the lips 2G, 30 liereinbetore described. In applying the closure 31 to the inner ring 2st l more the lips 33 of said closure through the recesses 29 of said ring and then impart to the closure a partial rotation, so as to carry the lips 33 away from the recesses 29 and along the flange 2S of said ring, whereby said tlange is enabled to tirinly hold the closure 31 in position. 1 provide the central portion ot' the closure With a. concavity 3st containing a linger piece 35 to 'facilitate the handling of the closure and its application to the other members of the structure.

Then the rings 21, 24; and closure 31 are in position across the outer end of the tubular portion 12 of the thimble they fully and absolutely close the thin'ible and present lapped joints AWhich enable the several parts to present a tlush front and also exclude dratts through the thinible. When it is desired to apply a store-pipe to the thimble the closure 31 will be removed, and it the opening thus lett is of proper diameter for the pipe, the thimble will require no further attention. lt, howeif'er, the pipe should. have a diameter greater than the hole through the ring 2-1, said ring will be removed, so as to increase the opening into the thimblc and vthe pipe may be inserted, if oli proper diameter into this opening. It the diameter ot' the pipe to be used is greater than that of the opening through the outer ring 21, said ring may be removed and the pipe inserted into the opening thus left. The rings 2l, 2l are both reducing and enlarging rings, the rings being one after another removcd for enlarging the opening for the pipe and one after another applied for reducing the opening for the pipe.

lllhat 1 claim as my invention and desire to secure by Letters-Patent, is:

A stove-pipe thimble comprising an iron tubular portion 12 haring integrally therewith at its outer end an annular ring faceplate 141 to rest against the outer face of the Wall around the opening therein receiving said tubular portion and also having at its outer end an annular outwardly projected section 15 containing' an annular recess 1G within which is an inwardly extending r, flange 1'1 having notches 18 at delinite points, an outer ring (21) fitted against said Ha nge and itself having an inwardly extending ange (23) which is notched through at i of said inner ring and engage the rear surdefnite points and at other points formed 2 face thereof; substantially as set forth. with outwardly extending lips to pass Signed at Alton, in the county of Belknap through the notehesin the said iange 17 and I and State of New Hampshire, this 2 day of 5 engage the rear surface of the saine, an inl Sept.
